  Methods

  Modifier and Type	Method and Description
  void	addLayoutComponent (Component comp, Object constraints) Adds the specified component to the layout, using the specified constraint object.
  void	addLayoutComponent (String name, Component comp) If the layout manager uses a per-component string, adds the component comp to the layout, associating it with the string specified by name.
  float	getLayoutAlignmentX (Container target) Returns the alignment along the x axis.
  float	getLayoutAlignmentY (Container target) Returns the alignment along the y axis.
  void	invalidateLayout (Container target) Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.
  void	layoutContainer (Container parent) Instructs the layout manager to perform the layout for the specified container.
  Dimension	maximumLayoutSize (Container target) Returns the maximum amount of space the layout can use.
  Dimension	minimumLayoutSize (Container parent) Returns the minimum amount of space the layout needs.
  Dimension	preferredLayoutSize (Container parent) Returns the amount of space the layout would like to have.
  void	removeLayoutComponent (Component comp) Removes the specified component from the layout.

    Instructs the layout manager to perform the layout for the specified container.

    Specified by:

    layoutContainer in interface LayoutManager

    Parameters:

    parent - the Container for which this layout manager is being used

  • addLayoutComponent

    public void addLayoutComponent(String name,
     Component comp)

    Description copied from interface: LayoutManager
    If the layout manager uses a per-component string, adds the component comp to the layout, associating it with the string specified by name.

    Specified by:

    addLayoutComponent in interface LayoutManager

    Parameters:

    name - the string to be associated with the component

    comp - the component to be added

  • removeLayoutComponent

    public void removeLayoutComponent(Component comp)

    Description copied from interface: LayoutManager
    Removes the specified component from the layout.

    Specified by:

    removeLayoutComponent in interface LayoutManager

    Parameters:

    comp - the component to be removed

    public void addLayoutComponent(Component comp,
     Object constraints)

    Description copied from interface: LayoutManager2
    Adds the specified component to the layout, using the specified constraint object.

    Specified by:

    addLayoutComponent in interface LayoutManager2

    Parameters:

    comp - the component to be added

    constraints - where/how the component is added to the layout.

  • getLayoutAlignmentX

    public float getLayoutAlignmentX(Container target)

    Description copied from interface: LayoutManager2
    Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

    Specified by:

    getLayoutAlignmentX in interface LayoutManager2

  • getLayoutAlignmentY

    public float getLayoutAlignmentY(Container target)

    Description copied from interface: LayoutManager2
    Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

    Specified by:

    getLayoutAlignmentY in interface LayoutManager2

  • invalidateLayout

    public void invalidateLayout(Container target)

    Description copied from interface: LayoutManager2
    Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.

    Specified by:

    invalidateLayout in interface LayoutManager2
